Eastron SDM72D-M-2-MID, Multifunctional electricity meter with bidirectional measurement, three-phase, 100A

Eastron SDM72D-M-2-MID

A three-phase electricity meter that, in addition to measuring active energy (kWh) and power (W), supports communication via RS-485 RTU Modbus , allowing easy integration into monitoring and control systems. This model is designed for direct measurement up to 100 A , making it ideal for applications where accurate consumption monitoring is required. The IP51 protection provides protection against dust and water, ensuring reliability in harsh conditions. In addition, it supports bidirectional measurement , meaning it can record both energy taken from the grid and energy returned to the grid.

The electricity meter meets strict European standards and requirements of the Measuring Instruments Directive 2014/32/EU (MID), which guarantees its accuracy and reliability.
